Scott Disick's moved on to his next fling, but he's keeping things consistent -- she's another hot young celeb still in her teens.


Scott and 19-year-old Sofia Richie were spotted chilling at the beach in Miami on Thursday after arriving together earlier in the day for an apparent couples vacation. The 2 was seen soaking up some sun and sharing a few kisses.


TMZ reports that the duo were seen hanging out around L.A. for weeks now, but there's never been any PDA. These Miami pics make it clear Scott's found the perfect follow-up to also 19-year-old Bella Thorne -- who he was dating over the summer.
